In this article, an approach to generate self-assembly cyclopalladated polythiophene imine monolayers (denoted as ITO@Pd-CPTIMs) is described. The monolayers were fabricated by combining self-assembly (SA), hybrid doping (HD), and electrochemical polymerization (ECP) called SA-HD-ECP. The catalytic activity and stability of the polymerized monolayers in the Suzuki coupling reaction were improved by modulating the structure and morphology in hybrid doping using different thiophene derivatives, concentrations, and sc [...]

The influence of different levels of alkalinity, expressed using M2O-to-binder ratio (n) and activator SiO2-to-M2O ratio (Ms), (M being the Na+ or K+ cation) on the reaction kinetics, compressive strength development and the reaction product formation in slag-based systems activated using alkali powders are discussed. The fundamental idea is to better understand one-part, “just-add-water” type alkali activated binders that are easy-to-use than the systems that rely on liquid activators. The difference in the behavi [...]

Antibody-mediated rejection represents a significant barrier to favorable long-term outcomes after kidney transplantation and remains the most common cause of allograft failure. Therapeutic apheresis techniques are commonly used, in combination with other treatments such as immunosuppressive drugs, in the pre-transplant and post-transplant protocols for the prevention and treatment of antibody-mediated injury. The rationale is to remove the donor-specific antibodies and the other inflammatory mediators, which inclu [...]

The global population of adults 65 years of age and older will increase dramatically over the next several decades, presenting economic and social challenges requiring sustainable solutions. Aging is a process in which everyone is already involved, it is a lifelong experience not just a later life occurrence. Changing world demographics illustrate that people are living longer, among the world’s young people, survival to age 80 is expected to be commonplace. This new found “longevity dividend” needs to be maximized [...]

Catalytic pyrolysis is an attractive alternative for converting biomass into energy and chemicals to replace fossil sources. This has encouraged the search for efficient catalysts that can directly remove oxygenated products during pyrolysis, since they are the main problem in the processing and use of the products obtained. The catalytic and non-catalytic pyrolysis of medium density fiber (MDF) over beta zeolite-supported nickel (3 and 5%) was performed using the biomass/catalyst of 1.0/0.2 ratio. The thermokineti [...]

Oesophageal cancer is the ninth most common cancer and the sixth most common cause of cancer deaths worldwide [1]. Over the past number of years, due to earlier diagnosis and better treatment, we are seeing improvements in the survival rates of oesophageal cancer, with more patients living longer post-esophagectomy surgery. Unintentional weight loss is a common unintended feature seen in patients post-esophagectomy done with curative intent. Many recent studies have demonstrated the links between the pathophysiolog [...]

The phase equilibria and structural transformations in the ternary ZrO2-CeO2-Eu2O3 system at 1500 °C were studied by X-ray diffraction and scanning electron microscopy in the overall concentration range. The system was found to constitute fields of solid solutions based on the tetragonal (T) modification of ZrO2, cubic (C) and monoclinic (B) modifications of Eu2O3, cubic with a fluorite-type structure (F) modifications of CeO2 (ZrO2), and ordered intermediate phase with a pyrochlore-type structure of Eu2Zr2O [...]

The novel coronavirus COVID-19 is a viral pathogen that first emerged in Wuhan, China in 2002 and has spread to 202 countries (as of March 28, 2020) [1]. Despite the fact that the 2005 SARS-CoV pandemic infected over 8,500 people, and caused over 800 deaths with billions of dollars in economic loss worldwide, as of 2015 there were still no clinically approved antiviral drugs, vaccines or monoclonal antibody therapies to treat SARS-CoV infections [2]. Antiviral medications that have been used to treat or control oth [...]

The parasitic protozoa in the genus of Leishmania have exceptionally favorable attributes for exploitation as a vehicle for safe and effective delivery of transgenically incorporated vaccines against infectious and malignant diseases. A dual suicidal mechanism was installed in Leishmania via genetic and chemical engineering in vitro for accumulation of photosensitizers, rendering them sensitive to dim light for inactivation. Leishmania so inactivated are non-viable, but immunologically competent to deliver vaccines [...]

In the recent past, laser therapy has made immense progress as it is known to change microcirculation, modulate vegetative parameters, and stimulate mitochondrial activity in the human body. This editorial briefly describes a new laser watch prototype (generation 2021), which can be used to perform continuous and simultaneous blood irradiation at the radial and/or ulnar artery of the wrist with different wavelengths of laser light. In a preliminary measurement, the increase in regional oxygen saturation at the croo [...]
